Basic Functions of Arduino

Configures the specified pin to behave either as an input or an output and other basic operation.

pinMode()

Description

Configures the specified pin to behave either as an input or an output. See the Digital Pins page for details on the functionality of the pins.As of Arduino 1.0.1, it is possible to enable the internal pullup resistors with the mode INPUT_PULLUP. Additionally, the INPUT mode explicitly disables the internal pullups.

Syntax

pinMode(pin, mode)

Parameters

pin: the Arduino pin number to set the mode...

In short What is Variable in Arduino

A variable is a named unit of data that may be assigned a value. variable is a named location in a memory where a program can manipulate the data. This location is used to hold the value of the variable. The value of the C variable may get change in the program. variable might be belonging to any of the data type like int, float, char etc.
